18. CHECK VALVE TIMING
HINT
Check the valve timing See: P0011.
NG -- ADJUST VALVE TIMING See: Engine, Cooling and Exhaust/Engine/Service and Repair/Overhaul/Disassembly
OK -- REPLACE ECM See: Powertrain Management/Computers and Control Systems/Engine Control Module/Service and
Repair/Removal
19. CHECK INTAKE SYSTEM
(a) Check the intake system for vacuum leaks See: Engine, Cooling and Exhaust/Engine/Intake Manifold/Testing and Inspection.
OK:
No leaks in intake system.
NG -- REPAIR OR REPLACE INTAKE SYSTEM
OK -- Continue to next step.
20. CHECK FUEL PRESSURE
(a) Check the fuel pressure See: Powertrain Management/Fuel Delivery and Air Induction/Testing and Inspection.
NG -- CHECK FUEL LINE
OK -- Continue to next step.
21. READ VALUE USING TECHSTREAM (COOLANT TEMP)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Data List / Coolant Temp.
(e) Read the Coolant Temp twice, when the engine is both cold and warmed up.
Standard:
With cold engine
Same as ambient air temperature.
With warm engine
Between 75锟斤拷C and 95锟斤拷C (167锟斤拷F and 203锟斤拷F).
NG -- REPLACE ENGINE COOLANT TEMPERATURE SENSOR See: Engine, Cooling and Exhaust/Cooling System/Engine -
Coolant Temperature Sensor/Switch/Engine Temperature Sensor/Service and Repair/Removal
OK -- Continue to next step.
22. INSPECT MASS AIR FLOW METER SUB-ASSEMBLY
HINT
Inspect the mass air flow meter sub-assembly See: Powertrain Management/Computers and Control Systems/Air Flow
Meter/Sensor/Testing and Inspection/On-Vehicle Inspection.
NG -- REPLACE MASS AIR FLOW METER SUB-ASSEMBLY See: Powertrain Management/Computers and Control
Systems/Air Flow Meter/Sensor/Service and Repair/Removal
OK -- Continue to next step.
23. CHECK VALVE TIMING
HINT
Check the valve timing See: P0011.
NG -- ADJUST VALVE TIMING See: Engine, Cooling and Exhaust/Engine/Service and Repair/Overhaul/Disassembly
OK -- Continue to next step.
